Active Directory photos not displaying in Outlook

Hi there

Unfortunately there is not enough detail to really give you a reply here,

Can you elaborate more ?

             Local AD, Local Sharepoint, 365 Teams,

How ad is synced to 365

You really need to give us a hint on where your at, what you've done this far etc.

That makes sense, and sorry for the lack of information.  This has gone on for a long time, so the software players have changed over the years.   As we move to do everything in Office 365, it's time for me to clean this up.  My current configuration is as follows:
1> Local domain controller with AD, running Azure AD Connect, on Windows 2012 RD Datacenter
2> Hybrid Exchange Server running Exchange 2010 on Windows 2008 R2
3> SharePoint Online using "Modern" sites
4> SharePoint 2010 (OnPrem)
5> Outlook 2016 local clients, Outlook 365 install, and Outlook Online
6> Teams local install and Teams Online

There is ONE odd piece to all of this; as we move to Office 365, our TEAMS program (both cloud and local install) seems to be displaying properly for everyone that has a picture in AD (passed to Azure).  It's just everything else that is having the problem, and that has gone on for years.  This is odd, since Teams I believe is pulling from Azure as is SharePoint, yet SharePoint doesn't display properly.

We use CodeTwo Active Directory Photos to upload photos to AD.  The Code Two used to be a local program that ran on our Exchange server, but is now an Office 365 add-on app since we moved to Exchange Online.

Its hard to establish an answer for all of this at once, so id consider breaking it up into manageble chunks:

Do images show up for local users in local sharpoint or outlook GAL
Exchange online - Do you see user images in OWA
